Which I can confirm because I just tried it. Wink

Code:
FORTHROM.BIN 16K relocatable
HRDFORTH.BIN 32K fixed at 0xE0000
FTH41ROM.BIN 16K relocatable
HRDFTH41.BIN 32K fixed at 0xE0000

A MultiMod owner reported recently that a stock MultiMod and a Forth module in the same machine caused a lockup. He reported it as an error because he had disabled the MultiMod with a poke zero. Hey, how was I supposed to know that was a use case I should handle? Smile

NB. Mike will get refund if no fix found.
